IRS CP05 Notice Explained: Why Your Refund Is Delayed

If you received an IRS CP05 notice, it means the IRS is reviewing your tax return before releasing your refund.

The notice usually means the IRS needs additional time to verify information on your return, including income, withholding, credits, or other tax details.

What Is an IRS CP05 Notice?

An IRS CP05 notice is a refund review notice. The IRS sends it when your tax return is being reviewed and your refund is temporarily delayed.

In many cases, the IRS states that no immediate action is required unless additional information is requested later.

Why Did I Get a CP05 Notice?

  • The IRS is verifying income information
  • The IRS is reviewing tax credits or withholding
  • Your return triggered additional review filters
  • The IRS needs more time before issuing your refund

Does CP05 Mean You Are Being Audited?

No. A CP05 notice is not necessarily an audit. It usually means the IRS is conducting additional verification before processing the refund.

How Serious Is CP05?

CP05 can be stressful because refunds are delayed, but many notices are resolved without major problems.

Ignoring future IRS requests, however, can create delays or additional issues.

How Long Does CP05 Take?

The IRS often states that reviews may take up to 60 days or longer, depending on the situation.

What Should You Do?

In many cases, the IRS says no immediate action is required unless the IRS later requests documentation.

You should still:

  • Review your tax return carefully
  • Keep copies of tax documents
  • Monitor your refund status

Will CP05 Delay Your Refund?

Yes. The IRS generally pauses refund processing until the review is completed.

Can CP05 Be Wrong?

Sometimes the IRS review is triggered by missing forms, employer reporting delays, or income verification problems.

Bottom Line

An IRS CP05 notice means your refund is being reviewed before payment is issued. While many reviews are resolved normally, you should monitor the situation carefully and respond quickly if the IRS requests additional information.
